OK - no need for a video, though it's a appreciated. I was wondering if it was something on my end since all the other options worked without issue. I knew the option is intended to reset the timer to 0, but when I used the option the timer didn't even flicker - I'll try re-doing the install this week and see if that helps. Thank so much for trying to replicate it.
Is this online related game content you are talking about?
I'd like to second this issue.
It's for offline mode. I had the exact same issue, I gave up and stopped playing blaming the game. I got it in a bundle so I wasn't too bothered if it didn't work.
The game for whatever reason doesn't save when cheats have been used. I could do a number of tracks save & quit. When I load the game again I'm right back where I started. I did this at least 5 times.
If the saves get uploaded (I think they do) could Codemasters check save files for figures that don't match. Eg My save shows I took 10 minutes to complete a run but my final time was only 5 seconds.
